RESUMO
Introduction: Despite the emergence of new treatments for HCV genotype 3 (HCV G3), there is still a lack of data about this particular subgroup in Brazil. Our objective was to describe clinical and sociodemographic variables and treatment profile of HCV G3 Brazilian patients. Methods: This was a descriptive, retrospective study, performed in a specialized center for HCV treatment in the South Region of Brazil. Medical records of patients diagnosed with HCV G3 were reviewed to collect clinical, sociodemographic, and treatment information. Results: Participants included total of 564 patients, with a mean age of 59.3 years (SD = 10.5). Cirrhosis was present in 54.4% of patients. The most common coexisting conditions were systemic arterial hypertension (36.6%) and diabetes mellitus (30%). Regarding treatment, 25.2% of the patients were treatment-naïve and 74.8% were currently under treatment (11.6%) or had received a previous treatment (87%). The most frequent ongoing treatment was sofosbuvir + daclatasvir (± ribavirin) (87.8%). Of the 388 patients who had at least one previous treatment, 67% achieved sustained virologic response in the last treatment. Caucasian / white, non-obese, transplanted patients, those with longer time since diagnosis and with cirrhosis were more likely to receive treatment, according to multivariate analysis. Patients with hepatocellular carcinoma were 64.1% less likely to be on treatment during the study period than those without this condition; patients with chronic kidney disease were 2.91-fold more likely to have an interruption of treatment than those without this condition. Conclusion: This study describes a large sample of Brazilian patients with HCV G3. Treatment patterns were mainly influenced by the presence of HCV complications and comorbidities.(AU)
